enginph Posted June 15, 2008 Report Share Posted June 15, 2008 Do you have to warm up rotary engine before taking off? And do you have to idle it after you stop? Quote Link to comment Share on other sites More sharing options...
mts Posted June 15, 2008 Report Share Posted June 15, 2008 You should do that to any engine for normalizing... Quote Link to comment Share on other sites More sharing options...
enginph Posted June 15, 2008 Author Report Share Posted June 15, 2008 You should do that to any engine for normalizing... Â I knew s.one would say that. For wankel i heard that this is more critical, is it? Â PS: I dont warm up, i do slow down before i reach the destination.. Â Quote Link to comment Share on other sites More sharing options...
mts Posted June 15, 2008 Report Share Posted June 15, 2008 The wankel normally runs turbos, but the problem is that if you just shut down, the heat has nowhere to escape from the driveshaft and it swells and damages the seals. When I used to work on steam engines, we had to mormalize for hours, to avoid hogging and sagging of the turbine shafts. Quote Link to comment Share on other sites More sharing options...
ing-schu@online.no Posted June 15, 2008 Report Share Posted June 15, 2008 Yupyup. The Renesis engine is also prone to foul the plugs if just briefly started and stopped again. Just like my KL Â I've also read somewhere that the Renesis engine is designed to run on a heavier weight oil than Mazda recommends. The recommendation is a result of environmental issues; thin oil reduces fuel consumption enough to save Mazda from paying penalty taxes or something like that. And apparently it is cheaper to swap some engines than paying said taxes... Strange world we live in. Quote Link to comment Share on other sites More sharing options...
mts Posted June 16, 2008 Report Share Posted June 16, 2008 Of course they want you to run lighter oils, then the engine fails sooner... it is a maintenance business.... they do not sell cars to just make profit once.... they sell cars so you will constantly maintain it.... and they hope it will be exclusively with them. They offer warranties as it is cheaper to fix it after than to make it right the first time, and it also "trains" the customer to return to the dealership for any issue....

ing-schu@online.no Posted June 16, 2008 Report Share Posted June 16, 2008 Apparently this was for saving taxes. Isn't the US tax system for car manufacturers based on average fuel consumption for each brand or something? As in higher average means more tax?

ing-schu@online.no Posted June 16, 2008 Report Share Posted June 16, 2008 No taxes based on pollution? I'm not talking purchaser taxes mind you, taxes for the manufaturers. Oh, nevermind Let's just conclude with rotaries liking heavier oils than Mazda recommeds. I am finding it harder and harder to trust these guys...

SteveSter Posted June 17, 2008 Report Share Posted June 17, 2008 In puerto rico they have insane car taxes depending on the type of car. Luxury cars have a tax, performance cars have another tax, coupes another all different amounts. For instance an M5 over there cost about 100k base because its considered a performance luxury car.

///BHRpowered Posted June 19, 2008 Report Share Posted June 19, 2008 as far as I'm concerned, every car, especially rotary and anything forced induction should go through a cool down, don't just pull in, park and turn it off, letting hot oil go through everything. let the car idle for a few minutes, give the oil a chance to circulate and cool down a bit. When driving the millenia I come in slow, then inbetween idling around to get the garage parking just perfect and leaving it sit another 2 it has worked well for me Quote Link to comment Share on other sites More sharing options...

mts Posted June 20, 2008 Report Share Posted June 20, 2008 This has been discussed in many RX forums, and enginehead conversations... of which BHR is not usually welcome Quote Link to comment Share on other sites More sharing options...
///BHRpowered Posted June 21, 2008 Report Share Posted June 21, 2008 I have never been banned from an RX forum  and I agree with camel, well except for the flooding part, if you've got fuel injection you won't have to worry about that.  I NEVER under any condition start any car then turn it off again a few minutes later, if I start a car its going to be driven or reach operating temp before it goes off again.  Generally speaking whenever I run the cars hard I take it nice and easy the last half mile or so getting to my house, and even then I still let it idle a good bit before shutting it off.

Troutman Posted June 23, 2008 Report Share Posted June 23, 2008 The reverse applies to warming up; no hard driving at all until full operating temperature - the transmission needs to warm up too and only light driving can achieve that.

ing-schu@online.no Posted June 23, 2008 Report Share Posted June 23, 2008 The RX8 has fuel injection of course, but still tends to get flooded if repeatedly started without being warmed up. Like I said, just like my KL, which also is fuel injected. I don't know about the KL, but it is a known issue on the RX8. Quote Link to comment Share on other sites More sharing options...
///BHRpowered Posted June 23, 2008 Report Share Posted June 23, 2008 enver once been an issue on any fuel injected car I'v ever owned, even though I never do retarded shit like start the car, move a few feet in the driveway, turn off, move again, go get mail etc like other retards, (5.2 v8) getting flooded maybe once  happened a decent amount on my old tractor though, annoying as fuck.  when it comes to start up I let all my cars idle for a good 30 seconds before going anywhere, and drive slow. With the millenia since it sits a bit longer I give it about 2-3 minutes before driving, and drive hella slow, nothing rough, low rpm's, right on shift points.
